The chemical reaction between potassium iodide and lead nitrate
Answers
Answer:
Potassium iodide and lead(II) nitrate are combined and undergo a double replacement reaction. Potassium iodide reacts with
lead(II) nitrate and produces lead(II) iodide and potassium nitrate. Potassium nitrate is water soluble. However, lead(II) iodide is
only partially soluble in water. Most of the lead(II) iodide precipitates out of the solution as a yellow solid (Equation 1).
2KI(s) + Pb(NO3)
2(s) → 2KNO3(aq) + PbI2(s) Equation 1
Explanation:
in the answer
Answer:
The potassium, iodine, lead and nitrate ions dissolve, and the potassium ions react with the nitrate ions to form potassium nitrate while the lead ions react with the iodine ions to form lead iodide. Lead iodide is insoluble in water and precipitates as a bright yellow solid in a double replacement reaction.
